Plasma Il-6 levels of CAD patient were significantly correlated with many Trans FA including RBC and plasma levels of C18:1 trans 9 (r = 0.46, r = 0.55, p < 0.001 respectively) and C20: trans 11 (r = 0.6, p < 0.001; r = 0.27, p < 0.05 respectively) as well as the plasma levels of C16:1 trans 11 (r = 0.28, p < 0.05) and the RBCs Trans FA (r = 0.37, p = 0.004) (Table 5). The gene discussed is IL6; the disease is coronary artery disorder.
